I merely pointed out that with some tight tolerance
cams and levers, you
have a similar problem - you can't tell by looking. "Difficult" in my
line above was a euphemism for "no hope"
Oh, OK, that is clearer now.
True, every word. But if you draw the distinction
there - digital vs.
analogue circuitry - the comment to which I was replying deserves your
reply as well. The previous poster (wasn't you, William, was it?) drew
the distinction at a higher level, and said something like "a digital
_machine_ either works or it doesn't. Apart from video, the results are
either right or wrong. With analogue/mechanical, things can be slightly
out but the machine will go on working" Video is another analogue
subsystem in a digital machine, just like a disk drive, and all that
that implies...
Yes, but everything is analog, including our favorite CPUs. Remember, you
can get a CMOS 4049 hex buffer to act as a (poor) amplifier!
Video, however, does not output digital results. Digital in, real world
out. Disk drives, when viewed as black boxes, are completely digital.
